I think none really wants to hurt other humans. The ones that does it does it because they feel forced to do so.
Therefore, convince them that they don't have to do so, and they won't kill.
Pacifism is a failed idea. I am not falling for it ever again. Crime will happen, no matter how much love and affection you shower upon the would be criminals. Nothing can be done about it.
Pacifism is how we should live. And as Ghandi said, "Be the change you want to see". If everyone do their parts the world would be a much nicer place. But thanks to attitudes like your nothing happens, because "there is nothing that can be done about it".
you my friends live in fairytales, that isn't real life
if ordered, they will kill
they do crime even without orders, look at american soldiers which pissed on muslim graves and shot civilians from their aircraft..
what would they do if someone ordered them to kill?
Yeah, they do that, because those people are assholes. But to be fair, not all soldiers murder because they think it's funny. They do it because it's their "duty". However, if they realize it's not their duty to murder a lot of things would change.
It's well known that during WW2 many soldiers just pretended to fire at the enemy because they didn't want to get blood on their hands.
Sure, drones, it's like a video game, and therefore it makes it a lot easier to kill. So let's just ban drones. Simple as that.
